Hmm. Not only is it an OBD I, it's a *Chrysler-specific* reset? Ok... do these ever show up on Ebay?
Here is a link to an Autoxray scanner.

In 2004 I bought a refurbished Autoxray 5000 scanner at a discounted price. It was compatible with OBD I and OBD II vehicles (pre 1996 and 1996 and later). It had the OBD II cable and GM, Ford, and Chrysler cables for OBD I vehicles. It had the specific Chrysler maintenance required reset feature which is DIFFERENT from the reset check engine lamp. Because of the low price I thought something awry and when I asked the tool was not upwardly compatible with the new CAN controller protocol mandated for all 2008 and later vehicles. This tool would interface with OBD II before 2008. I still bought it. The tool has worked well on both OBD I and OBD II vehicles. I have reset the maintenance required lamp on my 1991 Dakota.
Now look at this link for the EZ 5000 scan tool on Ebay. It is slightly different from the older model I purchased. It appears to have the OBD I & OBD II cables and is updateable and fully compliant with the OBD II CAN controller protocol used by manufacturers since 2008.
At least that is the claim. If you could verify this tool has the Chrysler maintenance required lamp reset feature, this might be a good purchase??? All precautions of buying used merchandise on Ebay should be followed.
I would suggest that you contact tech support at Autoxray and ask how you can verify a tool has the specific features you want. Tech support should be able to tell by the version number of the software which features such as maintenance reset, OBD II compliant, CAN controller protocol compliant, backwards compatibility, etc. Once you have the specific version number of the software tool features, contact the Ebay seller and ask for the version number of the software on the tool.
You can get an Autoxray tool to display software version number:
1. Press Power on key.
2. Press Config key.
3. Scroll down by using down arrow.
4. Highlight System Info item.
5. Press Enter
Software version number displayed. This tool may have it all.
I am in the next state north of you but still too far probably to get together and provide assistance. Happy Hunting!
